SPECIFICATION forming part of Letters Patent No. 698,579, dated April 29, 1902-. Application filed November 29, 1901. Serial No. 84,048. i (No model.)

To all whom it may concern:

Be it known that I WALLACE I. STIMPsoN, a citizen of the United States, and a resident of Milford, county of Worcester, State of Massachusetts, have invented an Improvement in Automatic Filling-Replenishing Looms, of.

which the following description,in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object the production of novel means for efiecting the actuation of the filling-replenishing mechanism of a so-called feeler-loom when the supply offilling in the shuttle has been exhausted to a predetermined extent.

In my present invention the filling in the shuttle intermittingly engages and moves a feeler until the filling is exhausted to a pre-j determined extent, whereupon an actuating device, previously movable in unison with the feeler, is moved relatively thereto by or through the filling-carrierin the shuttle, and

such relative movement is made operative through suitable intermediate means to effect a replenishment of filling.

lookingtoward the right. Fig. 5 is a detached detail of the movable stud forming a part of Fig. 6 is a top or plan view of the feeler. Fig. 7 is a similar detached view of one member of the actuating device, which is carried by and longitudinally movable relatively to the, feeler; and Fig. 8 is a side elevation of the membershown in Fig. 7.

Referring to Fig. 1, the loom frame A, breast-beam A lay A the shipper-lever S and its notched holding-plate H, attached to the breast-beam, the filling-feeder F to receive the filling-carriers b, the transferrer f, and

theoperating controlling rock-shaft cl, adapt- Fig. 3 is a vertical sectional view.

ed on a slide m, mounted in a guide b said edtobe rotated in the direction of the arrow 20 to effect a change of filling, are and may be all as shown in United States Patent No. 686,904, granted the 19th day of November, 1901,"the parts operating substantially as set forth in said patent.

The filling-replenishing mechanism is located at one side of the loom to transfer a fresh supply of filling to the shuttle S when the latter is in the adjacent shuttle-box While the feeler is mounted at the opposite side of the loom. p

The front wall of the shuttle-box E is pro vided with a longitudinal aperture or slot b and the shuttle has a slot s in its side wall to register with the aperture or slot 13 when the shuttle is in thebox B as shown in Fig. 1.

The rock-shaft d is provided with an up pivotally mounted a latch d rearwardly extended across the breast-beam and when in its operative position being adaptedto be engaged by a shoulder to on the weft-hammer a The latch is provided with a transverse projection (i which normally rests upon a 1 plate 90, secured to one end of a detent-lever d d f ulcrumed on avertical pivot (Z mounted on a bracket H secured to the holding-plate H, a spring s normally maintaining the inner end ofthe detent beneath the projection (i to thereby maintain the latch d inoperative or out of the path of the shoulder w on the weft-hammer.

The usual'filling-fork m is pivotally mountfilling-fork having a tail m to cooperate with the usual hook at, carried by the weft-hammer, when upon failure of the filling the are, is not tilted, as is well understood by those skilled in the art, the outer end of the slide engaging the end d of an-u'pturned arm (1 fast on the rock-shaft d, all substantially as in the said United States Patent hereinbefore referred to. The guide 12 forms part of a tle-box is provided with a depending web H, (shown in dotted lines, Fig. 1,) to which is suitably secured, as by a bolt 25, a feelersupport (shown separately in Figs. 2 and 3) and comprisingatubularbody portion at, having at its outer end a depending foot a, the tubular portion being closed at its rear end, as at a its opposite end being closed by a plate a (see Fig. 3,) detachably secured in any suitable manner to the depending foot a. The top of the part a is provided with a longitudinal slot a at right angles to the breast-beam, as clearly shown in Figs. 1 and 2, for a purpose to be described, the feeler being mounted to slide longitudinally in the tubular body portion a of the bracket. The said body is provided at its rear end with a hood a which overhangs the slot a said hood having a beveled portion a (see Fig. 3) immediately above the slot.

The feeler (shown separately in Fig. 6) consists of a tubular body f mounted to slide easilyin the tubular portion a of the bracket and having a bifurcated inner end to present two parallel branches f which project through a transverse opening a in the end a of the bracket-body. The lower part of the tubular body f of the feeler is provided with a transverse slot f and a hole f counterbored at f, Figs. 3, 4, and 6, is made in the top of the body above the transverse slot f. An annular recess f is formed in the inner end of the feeler-body (see Fig. 3) to form a seat for a coiled spring 8 the free end of the said spring bearing against a collar g, secured to the inner cylindrical end g of one member-viz., the actuator proper of the actuating device for effecting the operation of the filling-replenishing mechanism at the proper tim esaid collar being shown in Fig. 3 as held in place by the slightly-upset end of the part g Said cylindrical end g is socketed at to form a seat for a suitable spring S the opposite end of the spring bearingagainst the plate a The spring .9 normally tends to maintain the actuator butted against the inner end a of the supporting-bracket, while the springs at such time maintains the feelerbody in like position.

sumes the position best shown in Fig. 2, between the bifurcated portionsf of the feeler, so that the extremities of such portions and of the blade g are in alinement. An upright stud k is mounted in the hole f in the feelerbody and extends though a transverse elongated slot 9 in the cylindrical part g of the arm 9 the stud having a head which freely enters the slot a of the feeler-support, the lower end of the said stud having attached to it av segmental latch which is at times movable in the transverse slotf of the feelerbody, the stud constituting another member of the actuating device. At the lower end of the slot 9 the cylindrical portion g is transversely notched or cut away, as at g, and the latch, by reference to Figs.4 and 5, is shown Atsuchtimethebladelike or flattened end g of -'the,actuator' as-' as notched or cut out at or near its extremities at W. A lifting-spring s is seated in the counterbore f and acts against the under side of the stud-head 7t, normally tending to lift said stud, and when the parts are in the position shown in Figs. 2, 3, and 4 the latch 10 will bear against the circumference of the part g of the actuator to prevent the stud from rising.

The lever-arm d as shown in Fig. 1, extends across the top of the feeler-support a transversely to the slot a therein, and so long as the stud 7c of the actuating device is maintained retracted below the top of the feeler-support the detent d (Z will not be moved thereby. Whenever the shuttle en ters the box B the bifurcated end of the feeler and the blade-like part g of the actuator will enter the aperture 1) of the shuttlebox wall as the lay beats up, and such parts will also pass through the slot 8X in the sidewall of the shuttle to engage the filling, and as the lay completes its forward movement the filling will act simultaneously and uniformly upon the parts f g to move them toward the breast-beam in unison, so that their relative position will not be changed from that shown in Fig. 3 and the stud 7.. will still remain in retracted position. As the lay swings back the spring S expands and returns the actuator to its normal position, the spring 8 at such time acting to move the feeler in the same direction until the parts have again assumed the position shown in Figs. 1, 2, and 3. If, however, the actuator proper is moved longitudinally relatively to the feeler, it will be manifest that such movement will bring the notch g immediatelyabove the latch ki so that the latter is released, and the stud It; will instantly rise, by the expansion of the spring 5 projecting the stud-head above the top of the feelersupport a, and if such movement of the actuating device as a whole toward the breastbeam is continued, the stud-head moving longitudinally in the slot a the arm d of the detent will be engaged and said detent will be rocked on its fulcrum (Z in the direction of the arrow 75, Fig. 1, to therebywithdraw the plate from beneath the projection 01 releasing the latch d to be engaged by the shoulder to of the weft-hammer, and

' is properly boxed in the shuttle-box 13 the enlargement will be opposite the finger g of the actuator as the lay beats up.

Referring to Fig. 2, the filling-carrier comprises a barrel Z2, having a base or head If IIC eestve a and an elongated substantially cylindrical portion Z2 adjacent the head to receive the primary or initial winding of the filling. The annular enlargement b which is located between the ends of the part I), may be made as a part of the filling-carrier or the filling may be wound upon the filling-carrier in such.

a Way as to form an annular enlargement or ring at this point before any material traverse of the filling is instituted. In dotted lines in Fig. 2 the filling is shown at 8 and 18 on each. side of the annular enlargement, it being supposed that the filling has been woven ofi to u this point.

The filling is still of sufficient volume to prevent the enlargement b from projecting or standing out, as it were, beyond the surface of the filling as the lay beats up; but after the filling has been still further reduced the annular enlargement will so project, and it will engage theblade g of the actuator before the filling will engage the bifurcated portion f of the feeler, and con sequently the actuator g 9 will be moved toward the breast-beam on the beat up of the lay beforethe like movement of the feeler is instituted, and, as has been described, this forward movement will operate to release the stud k to operate the detent. Owing to the inclined or cam face a of the. hood on the feeler-supportthe stud cannot fully rise until it has been moved forward out of the hood, and, conversely,when the feeler and actuating device move toward the back of the loom by or through the action of the spring S after operation of the detent the cam-face a will act on the stud-head to gradually depress the stud against its lifting-spring s3 and into the position shown in Fig. 3,-so that the latch 10 will again becaught by the part g adjacent the notch 9 the notches k in the latch pers mitting the desired upward movement of the stud when released without increasing the depth of the notch g When the actuating device is engaged by the enlargement on the filling-carrier to move said actuating device relatively to the feeler, the spring 8 at such time operates to maintain the-feeler in the position shown in,Fig.3 until the actuator has been moved far enough to bring the re: leasing-notch g? over the-latch k and thereafter the continued movement of the said actuator g? g will act to carry with it the feeler.

My invention is not restricted to the precise construction and arrangement herein shown, and it may be changed or modified in various particulars without departing from the spirit and scope of my invention.

The mechanism herein shown is strong, durable, and at the same delicate in its operation.

Having fully described my invention, what Iclaim asnew, and desire tosecure by Letters Patent, is.
